GAs HEATING STOVE.

Application filed January 21. 1926. Serial No. 22,734.

The main objects of this invention are;

First, to provide an improved heating stove which is well adapted to be mounted upon a wall and for use in rooms such as y bathrooms and the like. i I i Second, to provide an improved heating stove which is very elficient and is compact and attractive in appearance. f

Objects pertaining; to details and soon omies of construction and operation of my invention will definitely appear from the detailed description to follow. The invention is clcarly defined and pointed out in the claims. I

A structure embodying, the features of my improvements is clearly illustrated in the accon'ipanying drawings forming a part of this application. in which:

Fig. l is a front elevation of a. gas or vapor burning heating stove embodying the features of my invention. I

Fig. 2 is a vertical section on a line corresponding to line 2+2 of Figs. 1, 3 and 4.

Fig. 3 is a horizontal section on a line corresponding to line 3-3 ofFigs. 1 and 2.

, Fig. 6- is an inside perspective view of the bottom of the casing. the screen for the air inlet openings thereof being partially broken away.

Fig. 7 is an end view of the reflector or inner back wall. I

in the embodiment illustrated, the casing comprises a back wall 1, end walls 2, 2, a bottom 3 and a top 4,.these parts being sheet metal stampings. i p

The back wall is provided with bead-like rolls 5 at its vertical edges which are engaged within the bead-like rolls 6 at the rear edges of the end walls 2, see Fig. 3. The top and bottom overlap the edges of these back and end walls, the edges of the top and bottom having rear flanges 8 and side flanges 9 embracing these walls, Tie bolts 10 are arranged through the beads and through the top and bottom walls clamping these parts together.

The bottom wall 3 has a series of air inlet openings 11 therein, these openings being covered by the shield 12. The shield is supported by tongues .13 struck inwardly be used successfully.

from this wall to engage the rear edge of the shield as shown in Figs. 2 and 6.

A base plate 14 is arranged in coacting relation to the bottom wall to provide a' burner chamber 15. Thetront edge of the bottom wall 3 has a. bead-like roll 16 therein which is embraced by a curved flange or roll 17 out-he base plate. I I I A. reflector or inner wall or fireback 18, preferably curved at its ends as shown in Fig. 3. is arranged upon this base which is flanged at its rear edge as 19. This reflector or ba k wall is arranged in spaced reat-ion to the back wall 1 of the casing providing an air circulating space 20. The top wall 4: has vent openings 21 therein through which the air circulated through this space 20 is discharged, this circulating space opening to the burner chamber 15.

Above the inner back wall 18 is a flue 22 having a flat bottom wall 23. This bottom wall has a bead-likeroll 23 at its front edge which is embraced by a coacting roll 25 on the trout edge of the top 4. -Uprights 26 having projecting ears 27 at the ends thereof a re $"ill'@(l to the edges of the reflector with the ears 2? at the ends-of the beads 16, 17, 24 and 25. Tie rods 28 are arranged through these beads and the cars 27, thus clamping the parts together.

The uprights 26 overlap the front edges of the end walls providing a finish there-for as well as a supporting member for the parts. The base plate 141. is further supported on lugs 29 on the end walls.

Cup-like radiating element and chimney supports 30 are mounted on the base plate and adapted to receive and support the chimneys 31 with their upper ends projectmg through openings 32 provlded therefor in the bottom plate 23 of the flue 22. This line opens at its ends through openings 33 in the end walls. These supports 30 also support the radiating elements or mantles 34% which are in the embodiment illustrated, formed of nichrome wire screens. Other mantles or radiating elements, however, may

The holders or supports 30 are provided with air inlet openings 35 for the admission of air to the chimneys between the radiating elements and the chimneys. The base plate 14 has a series of holes 36 in front of and adacent to the reflector, allowing air to circulate against the inner surface of the reflector. I use the term reflector in the broad sense. The same need not necessarily be a polished surface although I have found polished copper very satisfactory.

The burner 37 is arranged in the burner hamber and is of the Bunson type, having air inlet openings 38 within the burner chamber 15. the burner tube 39 projecting centrally of the burner body which has a discharge member 40 at one side carrying the tips 4-1 which are properly alined with the radiating elements 84.

A gas regulating member 42 is threaded into the burner body opposite the end of the tube 39 for regulating the discharge of gas It is not intended that this shall be adjusted as a valve but that it shall be adjusted according to the average gas pressure. The gas is controlled by the valve shown conventionally at 43.

With this arrangement of parts I provide a heater which is highly etlicient and is well adapted for use in rooms such as bathrooms. and can be readily mounted upon the wall. The combustion is etficient so there is little likelihood of noxious gases being discharged. There is also little likelihood of back-firing, the heater being lighted by opening the valve 43 and applying a match at one end or the other of the flue 22. I have found that the gas ignites readily with very little explosive effect or action.

here a plurality of chimneys is used as in the structure illustrated, the chimneys are preferably disposed in spaced relation and in spaced relation to the reflector so that the heat rays are effectively reflected and radiated. The chimneys are preferably of translucent glass resulting in a soft illuminating glow and at the same time of high heat efliciency.

I have illustrated and described my improvements in an embodiment which I have found highly satisfactory. I have not attempted to illustrate or describe certain embodiments or adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to which the invention relates to embody or adapt the same as may be desired.
